“…Furthermore, the relationship between the Ecological Footprint and biocapacity of a given geographic area can be used as a reference point to determine if the minimum conditions for sustainability, that is, Daly's core principles [20], are met within the associated socioeconomic system. The Ecological Footprint approach and its evolution can be traced in a number of publications [15,16,19,[22][23][24][25][26][27][28][29].…”

Ecological Footprint accounting quantifies the supply and demand of Earth’s biocapacity. The National Footprint Accounts (NFA) are the most widely used Ecological Footprint (EF) dataset, and provide results for most countries and the world from 1961 to 2014, based primarily on publicly available UN datasets. Here, we review the evolution of the NFA, describe and quantify the effects of improvements that have been implemented into the accounts since the 2012 edition, and review the latest global trends. Comparing results over six editions of NFAs, we find that time-series trends in world results remain stable, and that the world Ecological Footprint for the latest common year (2008) has increased six percent after four major accounting improvements and more than thirty minor improvements. The latest results from the NFA 2018 Edition for the year 2014 indicate that humanity’s Ecological Footprint is 1.7 Earths, and that global ecological overshoot continues to grow. While improved management practices and increased agricultural yields have assisted in a steady increase of Earth’s biocapacity since 1961, humanity’s Ecological Footprint continues to increase at a faster pace than global biocapacity, particularly in Asia, where the total and per capita Ecological Footprint are increasing faster than all other regions.

“…William Rees and Mathis Wackernagel co-developed the concept of the EF in 1996 [12]. Although it has been criticized as being insufficiently precise, the EF has for decades been one of the most commonly used sustainability indices [16]. The ecological footprint is an interesting measure of consumption as it effectively converts the consumption of all biological resources-from food, beef cattle and fish to peat and wood-into a measure of the amount of land and water that is required to support this consumption and the disposal of its related waste [17].…”

Ecological Footprint and Water Footprint of Taipei

Taiwan suffers from many natural disasters and is vulnerable to climate change. A continuous increase in its ecological footprint (EF) would pose numerous threats to the city. Taipei is Taiwan's most densely populated city. Whether its citizens are consuming more resources because of their high income and high degree of urbanization, thereby burdening the environment, warrants study. In contrast to most top-down EF analyses, in this study, 445 residents were surveyed to calculate their carbon, built-up land and water footprints. Gender, occupation, age, education level and personal annual income do not influence water footprint or EF. Moreover, an individual's water footprint is not correlated with his or her EF. The built-up land footprint that is obtained in this bottom-up study is similar to that in Taiwan's top-down national footprint account. However, the personal carbon footprint found herein is smaller than that in the national footprint account, because this study asked respondents only about consumption related to everyday activities. Since Taipei residents have a high income and high daily consumption, the water footprint herein is larger than the top-down water footprint. This bottom-up EF analysis reflects residents' daily consumption patterns and can be used in future urban decision-making.

This study focuses on shing activity in Algeria, speci cally the extraction of marine resources in Algerian costal and offshore zones. This sector is expected to meet several objectives and should contribute to Algeria's food security. Seafood is a signi cant source of protein and highly favoured by Algeria's coastal communities (Zaimen et al., 2021). However, with limited data available o describing the biomass that could be exploited, the pressure could eventually increase, on a common stock shared by all users and is already regarded as poorly studied (Chikhi, 2018). Therefore, this work includes the estimation of the marine footprint MF, which is the ratio between the demand of each shed species, known as the required primary production PPR (Pauly and Christensen, 1995), and the available biomass in terms of primary production PP of the marine ecosystems in Algerian shing waters. The latter is derived from the literature, relying on studies covering the considered area (Tellai, 1964; Kessouri et al., 2017). This study's main goal is to assess the sustainability of Algerian sheries, aiming at apprehending human demand on marine resources. The main study nding outline a PPR, PP ratio that doesn't exceed 1% demonstrating a sustainable shing activity. However, the obtained results, which tend to low MF percentages may imply that the available marine biomass in the Algerian shing zones are not fully exploited.
